The CP 010.09 Rigid All Board Envelope is designed to protect larger flat items that need to stay perfectly crease‑free in the post. Made from strong E‑flute corrugated cardboard in a smart brown finish, it offers reliable rigidity and impact resistance for a wide range of products.

With external measurements of 580 x 430 mm, this envelope includes pre‑creased folds that allow the depth to be adjusted up to 50 mm. This makes it easy to tailor the fit to the contents, helping to minimise movement and improve protection during transit.

It’s a practical choice for sending books, catalogues, calendars, artwork, prints, posters and other items that can’t be rolled or bent. The maximum internal size of 570 x 420 x <50 mm* provides generous space while keeping everything flat and secure.

Packing is quick and straightforward thanks to the integrated peel‑and‑seal strip, and customers benefit from a clean, simple opening experience with the built‑in tear strip.

*Effective internal size reduces as content thickness increases.
